Case Type   : 系统内部使用工具
Case Name   : gs_ctl stop指定-m的值为fast，stop备机是否成功
Create At   : 2021/01/19
Owner       : opentestcase015
Description :
    1.查看集群状态
    2.gs_ctl指定-m设置参数为fast，stop备机(备机执行)
    3.查看集群状态是否正常,备机是否已关闭
    4.环境恢复
Expect      :
    1.正常
    2.gs_ctl指定-m设置参数为fast，stop备机成功
    3.查看集群状态，备机关闭成功，状态为stopped
    4.成功

    Modified by opentestcase027 2023/5/8: step1查看集群状态前增加等待时间，待上个用例备机
                                     完成xlog redo,walreceiver发起连接后查看状态
